Parallel Shaft Spur Gear Reducers
Ondrives.US has been designing and manufacturing reliable, high performance gearboxes for more than thirty years. Our FF Series parallel shaft spur gear reducers (FF and FFS models) are designed for high efficiency with low backlash. Manufactured from durable, high quality materials and permanently lubricated for superior performance with minimal maintenance requirements the FF and FFS are lightweight but rugged. Our parallel shaft gear boxes will provide years of reliable service, even in nonstop or high cycle operation ideal for a wide range of power transfer applications (view catalog). If you’re unsure which parallel shaft gear reducer is right for your specific needs, view our Buyer’s Guide for ten important points to consider when choosing a gearbox. Another valuable reference, Inertia and the Use of Inertia Figures offers a formula for dealing with inertia in gearbox selection.
Custom Parallel Shaft Spur Gear ReducersWe also offer custom parallel shaft gearboxes that are tailored to your unique application and performance requirements. Contact our application engineers to discuss your custom specifications.
